Add clockevent drivers for i386: lapic (local) and PIT/HPET (global). Update the timer IRQ to call into the PIT/HPET driver's event handler and the lapic-timer IRQ to call into the lapic clockevent driver. The assignement of timer functionality is delegated to the core framework code and replaces the compile and runtime evalution in do_timer_interrupt_hook() Use the clockevents broadcast support and implement the lapic_broadcast function for ACPI. No changes to existing functionality.
